70results about How to "Optimize processing parameters" patented technology

Essentially all of the processing parameters which control processing of a source audio signal to produce an encoded audio signal are stored in an audio processing profile. Multiple audio processing profiles are stored in a processing profile database such that specific combinations of processing parameters can be retrieved and used at a later time. Audio processing profiles are organized according to specific delivery bandwidths such that a sound engineer can quickly and efficiently encode audio signals for each of a number of distinct delivery media. Synchronized A / B switching during playback of various encoded audio signals allows the sound engineer to detect nuances in the sound characteristics of the various encoded audio signals.

Based on the image quality simulation analysis method of the full-band optical processing surface shape error system link, it relates to the field of photoelectric imaging technology. The present invention designs the optical system structure according to the user index requirements, establishes the optical system link model, and processes the surface shape data based on the measured optical elements. , the low-frequency error simulation model and the medium-high frequency error simulation model of the mirror surface shape are established.

A method for processing a complex joint part of an aircraft comprises the steps of first milling a hexagonal part on a prepared blank to obtain a preliminary part, performing rough milling on the front and reverse side of the preliminary part with a drilled process hole to obtain a roughly processed part; performing heat treatment on the roughly processed part and then forming a plane, and then perform half finish-milling processing to obtain a processed half finish-milling part; after fine plane processing is performed on the processed half finish-milling part, performing finish-milling on the front and the reverse side, adopting a phi12R3 cutter to perform high-speed hole milling on the part, performing hole processing on the surface of a finish-milling lug piece and a recession, and processing a lug groove in two steps to obtain a processed finish-milling part; metering the appearance of the processed finish-milling part, and selecting the qualified processed finish-milling part toremove a process supplementing block to obtain a joint part. By reasonable selection of the cutter and optimized processing of process parameters, high-speed and high-efficiency processing of the joint part is achieved; meanwhile, a lug groove front and reverse side verification edge and verification hole process is added, and the front and reverse side butt joint errors are effectively reduced.
